Previously,
Self heals and self healing items will now activate a "Bacta Use" timer, denoted by a buff icon, on the character. If cumulative healing in excess of 10000 or more damage occur while this timer is active, additional self healing will have an increasingly reduced effect. Note that this effect only occurs on self heals and instant self healing items.
This ideas has been scraped. According to Tunso,
We've decided to shelve it for now and will explore different alternatives in upcoming publishes to alleviate and balance the issue of excessive healing capability. So healing will remain as it is right now, as will the healing cooldown timers for those that were updated.
